WinRAR is a data compression software. It is used to save storage space as well as time when you send and receive files, and to make backup copies. The first beta version appeared in 1993, although the stable version was not released until 1995. It has become one of the most frequently used programs of its kind across the world. The following are its most prominent features:
- Creation of packed ZIP and RAR archives and unpacking of compressed files.
- Compatibility with different compression formats such as CAB, TAR, ARJ, JAR, ISO, and BZ2 to name but a few.
- Support for security attributes and data flows in NTFS files.
- Protection of compressed files with AES encrypted password of 256 bits and with a digital signature.
- File locking to avoid secure manipulation and removal of sensitive data.

- Option to create self-extracting files and multivolume to split large files.
